L!',CAUTION
Always follow the basic precautions listed below
to avoid the
possibility
of
ph
ysical
Injury
to
y
ou
or
others,
or
damage
to
the
device
or
other property.
These precautions
Include, but are
not
limited
to
,
the
following:
Location
•
Do
not place the device
in
an
unstable position or fail
to
secure it properly
in
a potentially dangerous position
where it may
fall
even
if
the position is horizonta
l.
The
device may accidentally
fall
over,
resulting in damage
and/or injur
y.
• Do not use the speaker's handles f
or
suspended
installation. Doing so can resu lt
in
damage or injury
• Do not hold the bottom of the device when transporting
or
moving it.
In
doing so. you may pinch your hands
under
th
e device, and result in injury.
• Do not place the device in a locati
on
where
it
may come
into contact with corrosive gases or
salt a
iF
. Doing so
may resu lt
in
malfunction
• Before moving the device, remove all connected cables
• Always consult qualified Yamaha service personnel if
the device installation requires constructi
on
work, and
make
su
re to observe the following precautions.
- Choose mounti
ng
hardware and
an
installation
location that can support the weight
of
the device
-Avo
id locations that are exposed to constant vibration
- Use the required tools
to
install the device.
- Inspect the device periodically.
Conne
ct
ions
• Before connecting the device
to
other devices, turn off
the power for all devices. Before turn ing the power on
or
off for all devices, set
al
l volume levels to minimum.
• Use only speaker cables. Use of other types
of
cables
may
res
u
lt
in
fire
Handling caution
• Do not insert your fingers or hands
in
any gaps or
openings on the device.
•
Do
not rest your weight
on
the device or place heavy
objects
on
i
t,
and avoid use excessive force
on
the
buttons, switches or connectors.
•
Do
not use the speakers for a long period of time
at
a high
or
uncomfortable volume level. since
th
is can
cause permanent hearing loss.
If
you
experience any
hearing loss
or
ringing
in
the ears, consult a physician.
•
Do
not operate the device if the sound
is
distorting.
Pro
longed use in this condition could cause overheating
and result in
fi
re
• When choosing a power ampl
if
i
er
for use with this
device, make
su
re that the output power of t
he
amplifier
is lower than the power capacity
of
this device.
If
the output power is higher than
th
e power capacity,
malfunction or li
re
may occur.
• Do not input excessively loud signals that may result
in
clipping
in
the amplifier or cause the following:
- Feedback, when
us
ing a microphone
- Continuous and extremely loud sound
from
a musical
instrument, etc.
- Continuous and extremely loud distorted sound
- Noise caused by plugging/unplugging the cable while
the amplifier is turned
on
Even if the output power
of
the amplifier is lower than
the power capacity
of
this device (program). damage to
the device, malfunction or lire may occur.

by improper use
or
modifications to the device. or data

NOTICE
To
avoid the possibility
of
malfunction/damage to the
product, damage to data, or damage to other property,
follow the notices below.
Handling
and
Ma
intenance
• Do not expose the device
to
excessive dust or vibration,
or extreme cold or heat (such
as
in direct sunlight, near
a heater, or in a car during the day), in order
to
prevent
the possibility of panel disfiguration. unstable operati
on.
or damage to the internal components
•
Do
not place
vi
n
yl,
plastic or rubber objects
on
the
device, since this might discolor
th
e panel
• When cleaning the device, use a dry and soft cloth.
Do not
us
e paint thinners, solvents, cleaning fluids, or
chemical-
im
pregnated wiping cloths.
• Condensation can occur in the device due
to
rapid,
drastic changes
in
ambient
temperature-when
the
device is moved f
rom
one location to another, or air
conditioning is turned
on
or
off,
fo
r example. Using
the device while condensation
is
present can cause
damage.
If
there is reason to believe th
at
condensation
might have occurred, leave the device for several hours
un
til the condensation has completely dried out.
• When turning
on
the
AC
power in your audio system,
always turn on the power amplifier
LAS
T, to avoid
speaker damage. When turning the power off, the
power amplifier should be turned o
ff
FIRST
for the same
reason
• Be sure
to
observe the power amplifier's rated load
impedance, particularly when connecting speakers in
parallel. Connecting an impedance load outside the
amplifier's rated range can damage the power ampl
if
i
er.
• Protective Circuit
Al
l full-range loudspeakers are fitted with a
sel
f-resetting
poly switch that protects the high-frequency driver from
damage caused by excessive power.
If
a loudspeaker
cabinet loses high-frequency output, immediately
remove power from the power amplifier and wait for two
to
three minutes. This should be long enough to allow
the poly switch to reset. Reapply power and check
the performance of the high-frequency
dr
iver before
conti
nu
ing, with the power reduced
to
a level that does
not
cause the poly switch to interrupt the signal
• Air blowing out of the bass reflex
ports is normal, and
often occurs wh
en
the speaker is handling program
material with heavy bass content.
Connectors
• Use
on
ly Neutrik speakON plugs (NL4) for connecting
speakON connectors.

I Parallel
connection
of
speakers
The
signals of the phone jack and speakON connector are connected
in
parallel. The first CBR receives
the
signal f
rom
an amplifier (such as a power amplifier, a powered mixer, etc.) with the phone jack or the
speakON connector, and routes the signal to the second CBR. When connec
ti
ng CB
Rs
in parallel,
be
sure
to
check the load impedance the amplifier can drive. The nominal impedance of one CBR
is
eight ohms and the
total impedance of two parallel connected CBRs
is
four ohms.
In
this case, the amplif
ie
r must be able
to
dri
ve
less than four ohm load impedance.
